By this structure the conductor 28 is brought into electrical communication with the spark plug terminal 13, the sleeve'21 being pushed..

downwardly and then the device passed over the terminal 13.' and the sleever21 released,

whereupon the terminal 13 is gripped byA the structure within the sleeve21. p

Obviously, the stein 11 of the connecter device may be integral with or attached to the s ark plug conductor or terminal, while the exible conductor 28 may have a' rod or pin-like4 terminal to be inserted in the connecter device, as the terminal 13 is inserted in the connecter device in.
